A plumber in the UK has suped up his vehicle, broken a world record and now owns the fastest vehicle of its kind–a mobility scooter.

Colin Furze added a 125cc engine, five gears and twin exhausts to his scooter and rode it at a raceway near Northampton in the UK, where he reached a staggering speed of 113 km/h.

The scooter, which originally rolled at speeds of around 13 km/h, now rides a little shaky according to 32-year-old Furze. While it holds steady when going straight, “small steering movements have a big effect. Then you end up weaving all over the place. Let’s say it’s not very relaxing,” he said.
